ToaZZ whom "it may concern: 7

Be it known that I Tnoruas Pn'rnn EUSTEGE, a subject of the King of Great Britain and Ireland, residing in Hataitai, Wellington, New Zealand, have invented a new and usefill Improvement in Window Stays and Fasteners; and I do hereby declare the following to be a full, clear; and exact description of the same.

This invention relates to that class of casement window fastener in which a stay member slides upon a rod and assumes a position parallel or nearly parallel withthe rod when the sash is closed.

The chief object of the present invention is to provide a fastener in whiehthe forms a locking device when the sash is closed.

In the present invention the stay member is'arranged so that when the sash is closed the end of the member connected to the sash will lock into a bracket upon the frame or a sliding plate upon the stay member will form a locking member; The stay member is pivotally connected to the sash of the window'at one end while the other end is slidable upon a rod fixed to the frame or the arrangement may be that'the stay slides upon a rod fixed to the sash.

The invention is illustrated in the accompanylng drawings, where1n: V

is pivoted another bracket i on a pine, the stay member 1 being connected to the bracket 4 by a pin 6 passing through thelugs thereof. The other end of the stay member 1 has slot 7 in which slides a pin 8 the head 9 of which slides upon a vertical rod 10 securedin brackets 11 and 12 fixed tothe window frame 13. The pin 8 hasa knob 1:4: threaded thereon, the knob being prevented from unscrewing from the pin by means of a washer 15 riveted upon the end of thepin.

The pin18 passes through Ushapcd shoe '16 also sliding u'ponthe rod 10. By tighteningthe rod l l -theshoe forces togetherthe rod 10 and the stay member 1 so as to hold them rigidly together. A plate 17 is slidably mounted upon the lower end of the stay member 1 by means of pins or rivets 18' or 19, the latterforining an operating knob. These pins pass through a slot 20 in the stay member '1 and, if desired, a coil spring 21 may be attached at one end'to the pin 18 and at the other end to the stay member 1 and located in the slot 20 so as to retain the plate in its normal position; The lower end of the plate 20 has its front edge slightly bevelled at 22 and its rear edge bevelled at 23 as shown and is adapted to entera slot 24 in the bracket 12. I

In Figures 6 and 7, the p1n'5 is made 95 The end of the plate 26 is adapted to enter the slot 27 in the bracket 12. l

The operation is as follows Assuming the window to be open and the stay in the position shown in Figure land bevelled edge 23*upon the plate 17 contacts" withthe bevelled edge 28 uponthe bracket 12, and the plate will ride over the bracket 12 and drop into the slot 24. Y In the typeshownin Figures 2 and 4:, the weight of the plate will be suffieient tocause it to enter the slot and, if desired, the spring 21 may be introduced to make the action more certain, while in the type shown in Figures 6 and 7 the whole weight of the stay and accompanying parts will make the action certain, but if desired the spring 21 may be introduced around the pin 5 asshown.

Tocomplete .the locking,the operator may force the platel'? or 26, as the case may be, downwardly by means of the knob 19, the bevelled edge 22 tending to draw the sash against the frame. In order to make the fastening more secure he may tighten the knob 14. By the shape of the locking plate any looseness of the sash will only tend'to let the plate fall'lower and further tighten the window. V

-,To open the sash, the knob 14 is slaekened and the plate l? or the plate 27 disengaged by operating the knob 19 and the sash secured in the desired open position by tight ening the knob 14:. The slot 7 permits of further adjustment of the stay when the pin 9 isat the bottom of the rod 10, as indicated in Figi' rel; v t

Referring now toFigures 8 to 11, the stay is made in the same way exceptthat an extension rod 30 is provided and isfixedat its upper end in aiguide 31slidable upon the stay 1 Another adjusting knob 32 is threaded upon a pin having a head 33 and a shoe 3 1 slidablecn the extension bar 30,

these parts being of the same construction as those shown in Figure 10. In this case, the'extension member 30 is pivoted to a bracket 4: and when the sash is closed a cutawayportion 35 in the bracket 12 permits the stay to assume a closed position.- The lower endof the stay member 1 is provided with the bevelled portions 22 and 23 and is adapted to enter a slot/36 in the bracket 12.v Thebracket llhas and; 37 into which the upper'end of the stay memberllenters whenclosing in order to torm a guide to retain the member lin position to ride over-the plate 12 and ensure it entering the slot 36. a

Figure 1, shows this type of fastener in position the extension 30 being shown -.par tially extended. The operation is the.

.55 sameas in regardto .typesiin the previous figures, with the exception that theadjus'ting knob 32 must also be operated when openlng orclosing the sash. i Although the device. has been illustrated as applied' in a vertical position upon the w ndowtram i iobv i that ny o h .devices may-jbe employed upon thesill of the' w 1ndow. irame. In-such a case the. rod

-10 woul b x dizen allv 1 the Sill and in te d .qf the unix rsahiqi t t e end of the stay member would nepi voted to a bracket fixed to the bottom rail of the sash. In Figures 12 and 13 is shown a type of stay particularly adapted for use upon the bottom rail of the sash. This arrangement permit of the sash being opened and secured rigidly at almost any angle by means of a comparatively short stay. ing is shown in Figure 12 and by adjusting the stay to any position upon the rod 39 and the other end along the rod 10, any degree of opening may beobtained. The two rods 10 and 39 permit of the staybeing placed at an angle in relation to either rod that will give the maximum rigidity.

A slot 41 in the end of thestay permits the stay to slide backwardssufiiciently so that when the bevelled edge 23 contacts with the bracket 12 the stay willclear thebracket.

15 the stay is shown- Such an openrod '89. p In this casefa locking plate 1 guided upon the pin 38 and upon a pin a6.

A lip 47 on the end of the plate permitsot the plate being operated. What I claim s:- -p 1' 1.
